Information encoding method and apparatus, information decoding method and apparatus and recording medium

摘要

A method of encoding information of an input signal using a fixed number of bits for each unit time frame. Part of the encoded information of at least one second frame temporally consecutively or non-consecutively preceding or following a first frame is contained in the encoded information of the first frame. This eliminates fluctuations in the sound quality due to bit surplus/shortage resulting from quantization for achieving efficient encoding and decoding.
